Okay, folks... here's a good discussion topic for you;
Racial languages/religions/alignments.
I personally really dislike the "homogenous" races idea which seems to be present in a lot of TTRPGs, (D&D in particular). The idea that an entire race follows the same pantheon or speaks the same language, regardless of where in the world they're from just doesn't ring very true to me. This is why the idea of "racial" anything seems very incongruous to me. I have a hard time believing that the Elves of Silverymoon and the Elves of Cormyr speak the same language, let alone worship the same pantheon or have the same cultural structure.
In my campaign, several of the nonhuman races are extremely long-lived, which leads to a significant amount of linguistic stasis. Elves, in particular, live thousands of years, or at least they did until the last generation or so. But they travel and disperse themselves at about the same rate as humans, so widespread elves speaking a single tongue makes good sense to me. Likewise, dwarves live several centuries and are extremely linguistically conservative on the whole.
Despite this, I do have Ancient Elven (from long, long ago) and Old Dwarvish. And two elves (or whatever) from sufficiently far apart might not speak the same tongue; a long time ago, a pc elf arrived via long-distance teleportation and spoke a language that was similar to Elvish called Elfisti.
I do think some degree of the culture of a given race arises from their makeup- call it their genetics, their soul, or whatever. So the fact that my dwarves are almost universally conservative cultures, slow to change and with significant reverence for the ways of generations past, is not *just* a cultural thing- it's innate to some degree. Those innate traits are part of what make dwarves not-human.
As for Alignments, I don't use them anyway... I think they're WAY too "mechanical" to reflect true morality. I think the devs themselves even realised this; adding characters like Drizzt and gods like Eilistraee to pay lip-service to "moral complexity" within the cultures. But for people who use them, do you ever have issues with the idea of an entire race having the same moral compass? Or does it just not come up?
Did you play 3e? In 3e, a monster's alignment wasn't just "chaotic good"; it was either
always, usually, or
often (? might be misremembering that last one) chaotic good. So I would treat elves as "usually" chaotic good. Not all elves are, but the average elf you meet probably is.
No, I don't have an issue with a race having an innate moral position. In a game where there are actual demonstrable gods of moral positions, it only makes sense.
(Oh, and don't even get me started on the fact that there's a language called "Common"

)
There needn't be. The Common Tongue in my game is currently Imperial, but a while back, depending on where you started, it might be Forinthian, Strogassian, or Peshan- hell, it might even be Elvish, if you came from the right place.
Common Tongues are real- today, it's English. Not too awfully long ago, it was French (thus
lingua franca). At one point, it was Greek or Latin. But I will agree that, generally, a language actually
named Common would be weird.
